Performance‑Driven Software Engineering & Consulting
I’m John Brainerd. I build fast, reliable, and maintainable software that solves real business problems across medical, financial, government, and aerospace. From architecture to production, I own the outcome.
What I do
Architecture & Delivery
Full lifecycle ownership — requirements, architecture, development, testing, deployment, and support — with a focus on performance, reliability, and maintainability.
Modern .NET Solutions
Desktop (WPF/MVVM), services, and APIs in .NET 8/C#, backed by SQL Server and Azure. Strong focus on responsive UIs and robust data layers.
Automation & Data
OpenXML automation for Word/Excel, reporting pipelines, and integrations. Proven at scale — including massive performance wins.
GIS & Geospatial
Tools and workflows for geospatial analysis and visualization. Experience integrating with GIS platforms and raster/image processing.
Modernization
Refactoring and re‑platforming legacy systems — including NonStop/Tandem — into secure, supportable, and efficient solutions.
Advisory & Code Review
Hands‑on guidance, architecture reviews, and performance audits to de‑risk projects and accelerate delivery.
How I work
- Start with business goals; measure outcomes, not effort.
- Ship in small, testable increments with CI/CD best practices.
- Choose simple, proven tech — minimize accidental complexity.
- Own production quality: logging, telemetry, and graceful failure.
Selected wins
- Designed a voice identification system for OSHA training compliance.
- Delivered enterprise reporting with orders‑of‑magnitude speedups.
- Built resilient, auditable workflows in regulated environments.
